IM PROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 204,] 85, dated May 28,1878; application filed April 10, 1878.

.have invented certain new and usefuLImprovements in Horse-Powers, ofwhich the following is a specification:

Our invention relates to that class of horsepowers in which the power isobtained from one or more horses attached to the ends of levers or armsprojecting from a wheel or shaft having a vertical. axis, around whichthe horses walk in a circle. Horse-powers of this old style areextensively used for driving cottongins and other machinery which islocated on the second floor of a building.

Adjustable gearing, central supports, and various other expedients havebeen devised to overcome the difficulties arising from the carrying ofloads on the second floor, which interferes with the operation of thehorse-power as ordinarily constructed, and frequently causes damage orbreakage of machinery. We overcome the difliculty by providingaframeindependent of the building-timbers, except at one end, where it isfirmly supported by posts, which frame remains stationary, while thetimbers forming and supporting the upper floor may rise and fall with avarying load without affecting the independent horsepower frame or themachinery attached there to, at the same time retaining the old style ofmachinery, which is simple, cheap, and easily kept in order.

Our invention further consists, in combination with the saidindependent-frame horsepower, of rolling tooth-gearing, which adaptsitself to any irregularity or change in the position of the parts, andworks successfully even though the shaft be out of line.

In the accompanying drawings, Figure 1 is a perspective view of ourindependent-frame horse-power as applied Within a building. Fig. 2 is avertical section of the same. Fig. 3 is a perspective View, on a largerscale, of parts of the rolling tooth-gearing. Fig. 4 is an elevation ofmodified construction, and Fig. 5 represents detail views of the same.

A A represent timbers constituting parts of the house-frame. B B arebeams, attached to the cross-plate A by bolts at d, independent of themain frame. Said beams are placed at a suitable distance apart, to allowthe drum or pulley K to revolve between them, and are connected togetherby cross-ties, as follows: O is the cap or head-block, to which thecombined box and bearing D are attached to support the end ofmaster-shaft F, to which also the hanger and box E are attached tosupport the end of counter-shaft H. G is "a bridge-tie, on which theother end of shaft P; or the same object may be effected, as illustratedin Fig. 4, by means of chafingplates and set-screws a a secured to beamsA A and end of cap or head-block C, as shown in Fig. 4, so as to allowthe timbers A A to rise or fall as the weight on same may be diminishedor increased without disturbing the gear of the machine. We also proposeto use a bolt, b, with spiral spriu g attached to A and O, asillustrated in Fig. 5, to prevent swinging frame from tilting.

M is the master-wheel; F, shaft for same,

secured as before described. H is countershaft, on which the pinion hisfastened, working in segment t on master-wheel M. The bolt b and springa are shown in detail, also the combined box D and gudgeon for shaft.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the vertical mastershaft F and the independentframe B B, substantially as and for the purpose set forth.

2. The box D, cap 0, and beams B, combined, substantially as set forth.3. The combination of a vertical-shaft horsepower, FM, an independentframe, B B, for unto set our hands this 24th day of Novemsupporting theupper journal of said horsepower, and building-frames A A, to which thehorse-power frame or beams B are secured at; one end, leaving themindependent of said building-frame at the other end.

In testimony of which invention we hereber, 1877.
